Trevor Smith of Land Escapes will explain the benefits of living wall technology, the opportunities that Verticulture presents and how to incorporate the artfulness of living walls into your design repertoire, at this Tower Hill Botanic Garden class to be held Saturday, July 14, from 10:30 – noon at Tower Hill, 11 French Drive in Boylston. You will never look at a blank wall the same once you have the opportunity to “paint” with plants. Smith will discuss why living walls are not only an environmental benefit on a small scale by improving indoor air quality, or a large scale by reducing heat island effect, but also an innovative way to overcome landscape challenges in confined spaces with dynamic results. Fee is $15 for Tower Hill members, $18 for non-members, and you may register by calling 508-869-6111, or visiting www.towerhillbg.org.
